TECHNICAL FIELD

The present invention relates to an inflatable mattress structure. Morespecifically, the present invention mainly relates to an inflatablemattress with an improved structure.

BACKGROUND

Air cushion mattresses (also known as inflatable mattresses) are popularbecause they are lighter and less expensive than traditional mattresses.In order to provide better appearance or comfort, there have been manyprior art improvements to the air cushion mattress. However, many peoplestill find existing air inflatable mattresses uncomfortable and/orunstable. At present, air cushion mattresses on the market mainlyconsist of the top surface, the bottom surface, and the circumference atthe sides. The top surface and the circumference are connected by aninner wall, so that the top surface, the circumference, and the innerwall form a peripheral pipeline. Similarly, the bottom surface and thecircumference are connected by the inner wall so that the bottomsurface, the circumference and the inner wall form another peripheralpipeline. This type of air cushion mattress is widely used and simple toinstall and can be completed without special training and/or specialtools.

The air cushion mattress with the above structure forms a relativelysingle structure since the peripheral pipeline consists of the innerpipe, the top/bottom surface, and the circumference, which results in anunstable periphery, easy collapse, and stability defects. The inflatablemattress is prone to roll over when the user is lying or sitting nearthe edge of the inflatable mattress. Therefore, it is necessary tofurther research and improve the existing similar inflatable mattressstructure.

DESCRIPTION OF THE EMBODIMENTS

The present invention will be further described below with reference tothe accompanying drawings.

As shown in FIG. 1, an embodiment of the present invention is animproved structure of an inflatable mattress, comprising an inflatablemattress body 1. More importantly, as shown in FIG. 2 and FIG. 3, theupper edge of the inflatable mattress body 1 is provided with a firstannular pipe 3, and a second annular pipe 4 is also provided adjacent tothe first annular pipe 3. As shown in the figure, specifically, thefirst annular pipe 3 and the second annular pipe 4 are provided betweenthe top surface 11 of the inflatable mattress body 1 and the side edge13; and the second annular pipe 4 is connected to the first annular pipe3. The connection manner therebetween can be a ring-to-ring tangentconnection, and the contact area of the connection between the two ringscan also be enlarged to form a surface connection. The shapes of thefirst annular pipe 3 and the second annular pipe 4 need to be adapted tothe contour of the side edge 13 of the inflatable mattress body 1, thatis, the shapes of the outer contours of the first annular pipe 3 and thesecond annular pipe 4 are the same as that of the inflatable mattressbody 1. For example, if the inflatable mattress is circular, the shapesof the outer contours of the first annular pipe 3 and the second annularpipe 4 are circular, and if the inflatable mattress is rectangular, theshapes of the outer contours of the first annular pipe 3 and the secondannular pipe 4 are rectangular; the edge of the second annular pipe 4 isconnected to the side edge 13, and the connecting joint A (not shown thefigure) is located below the top surface 11. The edge of the firstannular pipe 3 is connected to the top surface 11, and the connectingjoint B (not shown in the figure) is located inward and upward of theside edge 13. The joint B can be in the inner cavity of the inflatablemattress body 1 or on the top surface. In addition, the inner cavity ofthe first annular pipe 3 and the second annular pipe 4 is communicatedwith the inner cavity of the inflatable mattress body 1; and aninflatable port 2 is provided on any one of the inflatable mattress body1, the second annular pipe 4 and the first annular pipe 3. Since theinflatable mattress body 1, the second annular pipe 4 and the firstannular pipe 3 are all communicated with each other, the inflatable port2 is installed at any position of the inflatable mattress body 1, thesecond annular pipe 4 and the first annular pipe 3 to play the same roleof inflating and deflating. Moreover, the inflatable port can adopt aconventional airbag check valve structure, or a three-in-one air nozzlecommonly used on an air cushion mattress, a built-in inflatable pump,and the like. Through the above structure, the inflatable mattresspresents five layers after being inflated, as shown in FIG. 4. As can beseen from FIG. 4, the inflatable mattress body 1 can also refer to theprior art by providing a plurality of independent supporting air columns5 in its inner cavity to increase the support force of the lying humanbody in the inflated state.

In this embodiment, by adding an annular tubular peripheral frame to theupper edge or lower edge of the inflatable mattress body 1, theinflatable mattress body 1 exerts a force on the upper side, the lowerside, and the side edges of the annular tubular peripheral frame afterbeing inflated, preventing the top and bottom edges of the inflatablemattress body 1 from being bulged after being inflated, so that the edgeof the inflatable mattress body 1 is more stable and less prone tocollapse after being inflated, preventing rollover when people sit andlie on the side.

Referring again to FIG. 2 and FIG. 4, in another embodiment of thepresent invention, in order to further optimize the stability of theedge of the inflatable mattress body 1 after being inflated, theinventor has improved based on the above structure. Specifically, whenthe first annular pipe 3 and the second annular pipe 4 are providedbetween the top surface 11 of the inflatable mattress body 1 and theside edge 13, the first annular pipe 3 is provided on the upper part ofthe second annular pipe 4, and the contour area encircled by the firstannular pipe 3 is smaller than the contour area encircled by the secondannular pipe 4, thereby utilizing the bevel structure formed by thefirst annular pipe 3 and the second annular pipe 4 to further improvethe stability of the inflatable edge of the inflatable mattress body 1.Based on the same principle as above, when the first annular pipe 3 andthe second annular pipe 4 are provided on the lower part of theinflatable mattress body 1, the first annular pipe 3 needs to beprovided on the lower part of the second annular pipe 4, and similarly,the contour area encircled by the first annular pipe 3 still needs to besmaller than the contour area encircled by the second annular pipe 4

Further, the manner in which the first annular pipe 3 and the secondannular pipe 4 are communicated with each other is not excessivelylimited. The technical purpose thereof is to simultaneously inflate thefirst annular pipe 3 and the second annular pipe 4 when air is chargedto the inner cavity of the inflatable mattress body 1 through theinflatable port 2. When the first annular pipe 3 and the second annularpipe 4 are filled with air, the first annular pipe 3 and the secondannular pipe 4 area abutted against the edge of the inflatable mattressbody 1, that is, by means of air pressure. The first annular pipe 3 andthe second annular pipe 4 form a limiting force on the body of theinflatable mattress body 1. In this embodiment, the first annular pipe 3and the second annular pipe 4 can be communicated with the inner cavityof the inflatable mattress body 1 through small through holes of anyshape, respectively. The second annular pipe 4 can also be communicatedwith the first annular pipe 3 through a small through hole, and then thefirst annular pipe 3 is communicated with the inner cavity of theinflatable mattress body 1 through a small through hole. Alternatively,the first annular pipe 3 is communicated with the second annular pipe 4through a small through hole, and then the second annular pipe 4 iscommunicated with the inner cavity of the inflatable mattress body 1through a small through hole. As mentioned above, the purpose of thethree methods is to realize the technical purpose of simultaneouslyinflating the first annular pipe 3 and the second annular pipe 4 whenair is charged to the inner cavity of the inflatable mattress body 1through the inflatable port 2.

Still referring to FIG. 4, in yet another embodiment of the presentinvention, based on the structure and principle of the first annularpipe 3 and the second annular pipe 4, both the upper edge and the loweredge of the inflatable mattress body 1 are provided with a first annularpipe 3 and a second annular pipe 4. In this structure, the first annularpipe 3 and the second annular pipe 4 at the upper edge of the inflatablemattress body 1 are provided between the top surface 11 of theinflatable mattress body and the side edge 13; and the first annularpipe 3 and the second annular pipe 4 at the lower edge of the inflatablemattress body 1 are provided between the bottom surface 12 of theinflatable mattress body and the side edge 13. In this case, the contourarea of the first annular pipe 3 is still smaller than that of thesecond annular pipe 4, and the first annular pipe 3 is provided at thelower part of the second annular pipe 4. Therefore, in this structure,the same stability can be achieved regardless of whether the inflatablemattress is used on the front side or the reverse side. Compared withthe structure in which the first annular pipe 3 and the second annularpipe 4 are provided on one side, this structure will increase theproduction cost to a certain extent, and is suitable for use on somehigh-end products.

As shown in FIG. 1, in use, the above preferred embodiment of thepresent invention is equivalent to having at least three independentairbags, namely an inflatable mattress body 1, a first annular pipe 3,and a second annular pipe 4. The three independent airbags describedabove can be filled at the same time when air is charged to theinflatable mattress body 1 through an inflatable port 2, which is in thestate as shown in FIG. 1. At this time, the first annular pipe 3 and thesecond annular pipe 4 serving as the annular tubular peripheral frameform a binding force on edge of the inflatable mattress body 1, and thelocal pressure from the edge can also be cushioned by the aboveperipheral frame, so that the edge of the inflatable mattress body 1remains stable and is not easy to roll over.
